CARLETON ELLIS, 0F LARCHMON T, NEW YORK, ASSIGNOR TO ELLIS-FOSTERCOMPANY, A CORPORATION OF NEW JERSEY.

BORATED INSECTICIDE FERTILIZER.

No Drawing.

Specification of Letters Patent.

Patented Dec. 21, 1909.

To all whom it may concern:

Be it known that I, CARLETOX ELLIS, citizen of the United States,residing at Larchmont, in the county of Vilestchester and Stateof NewYork, have invented certain new and useful Improvements in BoratedInsecticide Fertilizers, of which the following is a specification.

This invention relates to an insecticide and particularly to a drypulverulent material, having as its basis, Waste-lime borax materialobtained as a byproduct in the manufacture of borax.

In the preparation of insecticides, it is customary to mix aninsecticidal body such as paris green and the like with fiour-or otherfilling and extending material. In order to cheapen the cost of suchpreparation, I make use of a waste material which carries boraciccompounds having considerable insecticidal value. For this purpose, Ipreferably employ sludges having about the compositions shown below, oneof these being a typical sulfate of lime sludge and the other a typicalcarbonate of lime sludge.

Sulfate Sludge.

Carbonic acid(anhydrous) 33.85%

Sodium oxid 1. 16%

Water 2. 02%

Small amounts of chlorids and sulfates.

From the foregoing, it will be seen that a considerable proportion ofboracic material is present and I find that these bodies are especiallyadvantageous not only for their insecticidal properties but also toprevent the burning of vegetation by the arsenical compounds commonlyused for the purpose. As is well known, paris green and arsenate of limeand the like often burn the vegetation due probably to the presence ofarsenical material in too soluble form. In admixture with the lime-boraxwaste this burning action is not in evidence.

A suitable formula illustrative of my invention consists of 96 parts oflime-borax waste, 5 parts of paris green and 1 part of lead arsenate. 90parts of lime-borax waste, 8 parts of lead arsenate and 2 parts of limearsenate. Another formula consists of 94 parts of limeborax Waste and 6parts of copper arsenate. Still another formula consists of 94 partslime-borax waste, 4 parts of paris green, and 2 parts of lime arsenate.A very simple composition is made by mixing 5 parts of paris green with45 parts of sulfate lime waste and 40 parts of carbonate lime waste.

Iron oxid or other coloring matter may be added if desired.

In order to give the insecticide fertilizing properties, fertilizingsalts such as sulfate or nitrate of ammonia, sulfate or chlorid ofpotash, phosphate of ammonium, phosphate or superphosphate of lime,etc., may be added.

The lime sludges may be treated by a precipitation process so as to formthe arsenical or other insecticidal body on the particles of the sludgematerial, adding for example, a solution of soda arsenate to the sludge,and then introducing the solution containing sufficient sulfate ofcopper to precipitate the arsenate on the particles of the sludge. The

sludge may then be dried or if desired may first be washed to remove thesulfate of soda and then dried.

Other materials may be incorporated with the compositions aboveindicated or with the lime sludge material alone as for example, thesolid condensation product of creosote with formaldehyde, or such saltsas fiuorid of sodium or potash.

A mixture of lime-borax waste 50 parts, ground zinc oxid 40 parts andammonium I sulfate 3 parts, ammonium chlorid 3 parts and potassiumsulfate 4 parts makes a fairly effective insecticide which possessesfertilizin properties.

hile other filling and extending materials may be employedlILCOIljIlIlCtlOIl with the borax waste including other sludgematerials, I prefer to use this material as the principal component.

Another formula consists of The composition is preferably applied in thedry powder form by dusting over the plant leaves. Its property ofadhering to vegetation is marked and is an advantage of 5 some momentaspowders not possessing this property are often removed by wind or rainbefore destruction of insects is complete.

Having described my invention to the details of Which description I donot wish to 10 limit myself, What I claim is 4 1. An insecticidecomprising the herein described waste lime borax material and anarsenical.

3. An insecticide comprising the herein described Waste lime boraxmaterial, a metallic arsenate and a soluble fertilizing body,

all in a powder form.

In testimony whereof I have affixed my signature in presence of twowitnesses.

CARLETON ELLIS.
